LP2986
Micropower, 200 mA Ultra Low-Dropout Fixed or
Adjustable Voltage Regulator
General DescriptionThe LP2986isa 200mA precision LDO voltage regulator
which offersthe designera higher performance versionof
the industry standard LP2951.
Usingan optimized VIP™ (Vertically Integrated PNP) pro-
cess,the LP2986 delivers superior performance:
Dropout Voltage: Typically180mV@200mA load,and1@1 mAload.
GroundPin Current: Typically1mA@ 200mA load,and
200μA@10mA load.
Sleep Mode: The LP2986 draws less than1μA quiescent
current when shutdownpinis pulled low.
Error Flag:The built-in errorflag goeslow whenthe output
drops approximately5% below nominal.
Precision Output:The standard product versions available
canbe pin-strapped (usingthe internal resistive divider)to
provide output voltagesof 5.0V, 3.3V,or 3.0V with guaran-
teed accuracyof 0.5%(“A” grade)and1% (standard grade) room temperature.
Features Ultralow dropout voltage Guaranteed200mA output current SO-8and mini-SO8 surface mount packages<1μA quiescent current when shutdown Low groundpin currentatall loads 0.5% output voltage accuracy(“A” grade) High peak current capability (400mA typical) Wide supply voltage range (16V max) Overtemperature/overcurrent protection −40˚Cto +125˚C junction temperature range
Applications Cellular Phone Palmtop/Laptop Computer Camcorder, Personal Stereo, Camera
